OIL-BURNER.

ToN, a citizeuof theV United States, and a resident of Chicago,` in the county of Cook und State of' Illinois, have invented certain newand useful Improvements in ()l Burners, of whichthe following is a specf'- cation.

Myinve'ntion relates to` oil burners, and

more particularly to sucli as include there with means for generating ygus from the oil and for Acomminglng nir and gas in advance of the burning'opeiation, While the present improvements iniiy' bey employed elsewhere andranges, tlicillustrated .embodiment of the same is in a form especially. adapted for such use, thereby"substituting for coal or wood in such fireboxes liquid fuel yielding n, flame of burning gas( The )rincipal objectsof vthese improvements are to provide an voil .burner vof the generlil 'class4 described `:which is of high' efficiency, of simple construction,-.ivliicliglias parts readily removable, asfiorfcleaiing for repair, and which'.maybeieasily .oper .ite l.

Fig. 2 is an end elevation :is viewed from the left hand end of Fig. 1; e

1 `ig. Seis a rear side elevation, a portion of one of the burners being broken away to show interior parts.; and

Fig. 4 is a medial transverse section as on the line 4-4 of Fig. 3 viewed in the direction of the arrows. V

The substantially horizontally disposed base or support 10 having depending legs 1l 65 is suitably an iron casting, tlielegs 11 being adapted to rest upon the fire box grate of the stove or range or upon any other suitable support. In order that several fiaines may beeniployed for heating purposes at the same time I provide 'a plurality of burner heads, as l2, 12,A a description o-one thereof suilieing for both. Such burner head co1nprises a topl plate 14, a bottom plate 15, an limer perforated side wall 16, and an outer rpefrforated,iside wall 17, the several Walls y)eiligfspaeed apart to. provide a liollow in.- .yerior foi."co1umingled gas and air, the top nd bottom Wallsl and -15 preferably being annularly recessed as at 18,19, 20 and 21 to y 80 l A lu :toiilmo:late' edge portions of the walls 10 and 17, these burner head parts being held in assembled relation by, screws 22. 4Each of the burner heads 1 2, 12 is held upon the and 27.

A n ianifold 30 is substantially horizony tally disposed to Vthe rear of the niain support 10 and has upturned extremities contacting the bottom plates 15 resliectively.

Bolts 211 secure the manifold.rigidly in association with'tlie burnerheads. AnV opening .3i-{in euoli bottoni wall 15A is infconimunica- "timi'vivith tliefhollow interior of the mani'- A sliding plate valve deviceli,v of '95 ate sl1a pe,.is,niofvably;positionedupon x-bottoin wall v15.

The 4manifold `30 opensfinto a mixing ifold; and turnsfforward preferably above ofthe bottoniof the The walls forming.tl1e manifold and mixing chamber dreformed ns a The manifold 30 has an opening 42 in the topthereof registering with an o enlng leading to the hollow interior 43 of t e gasgenerating burner 44. This generator part 44 is also suitably a casting. For holding the core to provide the hollow interior 43 it is advantageous to leave a circular opening in each end of tliepattern of the burner part 44, and subsequently close these openings in the casting as by means of plugs 45, 45 (Fig. 3). A plurality of preferably transverse narrow slot-like openings 46 are formed in the top portion of the burner device 44 to the hollow interior thereof Whereby mixed gus and air from the manifold 30 I, will issue from these burner openings 46 `I provide also two trough-like recesses 4 47 longitudinally of the generating burner 4=l adapted to hold asbestos or the like 48, which is saturated with the combustion .liquid and ignited in order to start the operation of the device. Other recesses 50 for containing asbestos or the like 51 sare formed in the main support 10, the combustion liquid also being applied to these auxiliary primary generating burners in order further to heat the gas generating tube initialiy.

The gas generating-tube 52, suit-ably an iron' pipe, is positioned immediately above the generator burner 44. One arm 53 thereof extends substantially over one of the asbestos generator burners 51 and then 'turns downward, as at the part 53" thereof, sutilciently away from'the .fia-me area where a union or any approved form of connection .5ft unites this generator pipe with the oil supply pipe 55, a valve 56, understood to be outside the stove or range, controlling the supply of the fuel oil to the generator pipe. It isv to be understood that a supply of' fuel oil, such as kerosene, for operating the device is contained in a- 'suitable tank and Hows by force of gravitation or by air pressure within the tank to the valve 56,

Another extension 58`;of the generator pipe 52 is turned substantially over the other one of the asbestos generator burners 51 and is then turned downward as at the part 59 thereof. The end of theextension 59 is Closed, as at 60, bv anysuitable wall or plug.

Y A small hole 61 is .formedin the pipe 59 in such l sition that gas issuing therefrom is direcf substantially e'entrall into the horizontal leg of the mining ciamber 40;4 Means for -supplyingair to the mixing chamber to be commingled with the lgas issuin' therein'to from 'the hole 61 comprise the ho low 'coupling' piede 63 .held upon the A slanting opening 65 is formed in the top. wall of this piece 63 whereby the pipe 'ex-,fv tension 59.1nay pass into the hollow inte xrior and 'rest upon the bottom portion thene'- pf. No other. holding means are required for maintaining the generating pipei52 and its several extensions in the desired operative position. Two hollow arms 66 extend' from the head piece 63, each thereof toward one of the legs 11, these extensions 66 preferably'being somewhat li-attened so that the opening 67 (Fig. 2) at the end of eachthereof is substantially of the same shape and area as is the opening 33 in the bottom wall of each of the burners 12 (Fig. 1). l

A lever 70 is pivoted, as by a shouldered -serew 7l, to the inner wall of ea'h of the that if the lever 36 ismoved sov as to open or close, wholly or in part, the opening 33 in one of the burners the air intake opening 67 (Fig. 2) below it will be opened or closed to the same extent. Bythis simple construction I provide means for simultaneously va rying the amount of air entering the airintake opening 67 proportionate to the amount of eonxbiiied gas-and-nir being consumed, or, in' other words, `proportionate to the amount of gas issuing into the burner head or heads 12, and thus the same character. of liame issuing from the burners 12,' Y 12, may be maintained whetherthe liarne is high, medium or low.

It is pointed out that to 'secure the advantageous substantially non-smoking blue flame' at the burner heads, as 12, and-Which the present apparatus is adapted to provide, the

-amount of'air mixed with the gas in the mixing chamber must suitably proportioned., If too little air-is mixed with the gas a, smoking-yellowish flame will issue from the burner fheads, while iftoo much air is supplied a` reddish flame will result. l" have found from eXperimentthat where the air opening 67 is substantially ofthe same area as thel as-and-air openin 133 in' the burnerstlie desired blue'iame .wil result,
